Description

Technical Field

[0001] This utility model relates to the technical field of gantry machining centers, specifically to a dual Z-axis device for gantry machining centers. Background Technology

[0002] In high-end manufacturing sectors such as aerospace, automotive molds, and wind power equipment, the demand for machining large and complex structural parts is increasing, placing stringent requirements on machining accuracy, production efficiency, and consistency in batch processing. Traditional single-axis gantry milling machines lack sufficient bidirectional synchronous control capabilities, making it difficult to achieve efficient machining when performing symmetrical machining and high-precision surface treatment of large workpieces. For example, in the milling of aerospace components, single-axis machine tools require multiple clamping and positioning operations, which not only consumes a significant amount of time but also easily leads to cumulative errors, failing to meet the precision requirements of precision machining. In the cutting process of automotive molds, single-axis machine tools struggle to balance machining efficiency and surface quality, resulting in extended production cycles and increased scrap rates.

[0003] Furthermore, the dust collection systems of traditional gantry milling equipment are mostly single-structure systems, unable to coordinate different processing methods such as milling and cutting, and unable to efficiently collect debris and dust generated during processing. During milling, chips fly wildly and are difficult to collect effectively; during cutting operations, the generated dust can create a harsh processing environment, affecting the health of operators, and can also lead to frequent equipment failures due to dust accumulation, reducing processing accuracy and equipment lifespan. Summary of the Invention

The screw motor 304 is fixed to the upper end of the saw blade Z-axis vertical beam 305. When the screw motor 304 operates, it drives the saw blade Z-axis transmission screw pair 303, causing the saw blade Z-axis vertical beam 305 to move along... The saw blade moves along the Z-axis. A reducer 306 is bolted to the lower end of the saw blade Z-axis vertical beam 305. Its output shaft passes through a pre-drilled hole in the center of the dust collection flange 307 and connects to the upper end face of the housing 308.

The upper dust collection flange body 307a has two dust collection pipes 311 with sealing interfaces on its upper part. The upper part of the saw blade Z-axis vertical beam 305 has a reducing tee 312. One end of the two dust collection pipes 311 extends into the dust collection flange 307, and the other end is connected to the reducing tee 312 through a corrugated pipe with good sealing and flexibility. The reducing tee 312 is also connected to an external dust collection device. The lower part of the dust collection flange 307 has two dust collection pipes 315, which are connected to the saw blade dust collection pipe 314 through a flexible hose. The output shaft of the saw blade main motor 309 is also provided with a saw blade dust cover 313. The saw blade dust cover 313 is fixed to the motor housing on one side of the motor output shaft by bolts and other connecting parts. Two suction pipes 314 are provided on one side of the dust cover 313. The two suction pipes 314 are installed behind the dust cover 313 and form a ventilation channel with the dust cover 313.

[0046] The lower part of the saw blade dust hood 313 is provided with a free-falling dust suction baffle cover 316, which is fitted inside the dust hood 313. The dust suction baffle cover 316 is provided with a downward linear guide rail pair 321.

The slider on the downward linear guide rail pair 321 is rigidly connected to the side of the dust hood 313.

These protective covers are installed by bolts, clips and other methods, which can effectively block the flying debris during the processing and protect the internal components.

[0049] Working principle:

[0050] When performing machining operations such as milling and drilling, the lead screw motor 204 starts, and the motor output shaft drives the transmission lead screw of the mechanical Z-axis transmission lead screw pair 203 to rotate through the coupling. Under the drive of the lead screw, the mechanical Z-axis slide plate 201 connected to the lead screw nut seat moves along the linear guide pair 202 in the Z-axis direction, thereby driving the mechanical Z-axis vertical beam 205 to move, thus adjusting the position of the tool on the tool mounting shank 208. After the mechanical Z-axis spindle motor 206 is powered on, its shaft drives the mechanical shaft 207 and the tool to rotate at high speed for cutting. During the machining process, the mechanical Z-axis auxiliary cylinder 209 monitors in real time and adjusts as needed. The air pressure helps stabilize the position of the Z-axis vertical beam 205 of the machine, preventing it from shaking. At the same time, the lifting cylinder 214 can control the position of the dust hood 213 by extending and retracting according to the height of the workpiece and processing requirements. When it is necessary to collect debris and dust, the lifting cylinder 214 extends, driving the dust hood 213 down and closing the movable protective plate 217. The two dust suction pipes 216 are connected to the external dust collection equipment through the corrugated pipe and the reducing tee 215 to promptly suck away the debris and dust generated during processing. The booster cylinder 210 continuously provides high-pressure gas to the tool changing cylinder air circuit. When it is necessary to change the tool, the tool changing cylinder uses high-pressure gas to quickly release and change the tool.

[0051] When sawing is performed, the lead screw motor 304 starts, and its output shaft drives the transmission lead screw of the saw blade Z-axis transmission lead screw pair 303 to rotate through the coupling. This causes the saw blade Z-axis slide plate 301, which is connected to the lead screw nut seat, to move along the linear guide pair 302 in the Z-axis direction, thereby driving the saw blade Z-axis vertical beam 305 to move and adjust the position of the cutting saw blade 310. After the saw blade main motor 309 is powered on, its main shaft drives the cutting saw blade 310 to rotate at high speed for sawing. The saw blade Z-axis auxiliary cylinder 319 helps stabilize the position of the saw blade Z-axis vertical beam 305 during sawing to ensure sawing accuracy. Dust collection flange 3 07. The dust collection system, consisting of the saw blade dust hood 313 and its related dust collection pipes, begins to operate. The upper and lower dust collection flanges of the dust collection flange 307 can rotate relative to each other to adapt to different dust collection needs. The second dust collection pipe 311 on the upper dust collection flange is connected to the external dust collection equipment through a corrugated pipe and a reducing tee 312. The fourth dust collection pipe 315 at the bottom is connected to the third dust collection pipe 314 on the saw blade through a flexible hose. At the same time, the third dust collection pipe 314 on one side of the saw blade dust hood 313 also collects the sawing debris and dust, which are then discharged in a timely manner through the entire dust collection system to ensure a clean processing environment and normal equipment operation.
